- Hello,
-
- This is my first post to this news group, and from reading it,
- there seems to be a lot of expertise here.
-
- Hopefully, someone can help me.
-
- I have System 7.0 running on a IIcx, 4MB RAM, and with MODE32. I just
- tried to use the virtual memory feature, and had several problems. I
- turned on 32 bit processing, and enabled MODE32, and increased the
- *total* memory to 12MB.
-
- 1) Although the memory control panel says 'total memory,' the entire
- 12MB seemed to be subtracted from my hard drive, ignoring the 4MB of
- real RAM I have.
-
- 2) The Mac doesn't seem to release its VM on the hard drive. After I
- ran some memory intensive applications, I closed them all and tried
- to open one small application, and I got a message saying insufficient
- memory (and not the message saying an application prefers X amount, but
- only Y amount is available), and the application would not open. I
- checked the Finder, and it said the largest unused block was > 8MB, and
- this app only needed 342K!!!!
-
- 3) I couldn't seem to cut and paste. I tried cutting something from a
- paint program, and pasting it into the scrapbook...after several tries
- and 'out of memory' errors, that finally worked. Then I tried to copy
- the picture from the scrapbook and paste it into a PICT resource inside
- ResEdit, and I couldn't get it to work (the picture was about 700K).
- It was like the clipboard just kept being erased.
-
- 4) VM seemed to bite into harddrive space which I didn't allocate to it.
-
-
- Any help would be appreciated. I don't know what System 7.0.1 fixes, but
- I didn't even know it was out until reading this news group. Does it patch
- VM?
-
- Thanx in advance,
-
- Lee
